IMPROVEMENT IN WATER-WHEELS.

` The Schedulereferre-d to in these Letters Patent and making part ofthe same.

winch 'the following ls a full, clear, and. exact descriptio'n,referencebeing had to thev accompanying drawing forming part of thisspecification, and in which- Figurel represents a side view of awater-wheel cor'lstructed iu accordance with my invention Figure 2,-aplan of the same and Figure 3, Aa vertical section thereof.

`buitablle letters of reference indicate corresponding My inventionrelates to turbine water-wheels, and consists in a novel construction ofthe gate, case, and buckets of the wheel, whereby the water is receivedonto the buckets in opposite lateraldirections and l obliquely inforward 4and downward courses, and is discharged centrally, outwardly,and downwardly therefrom. l

' .Referring to the accompanying drawing- Afreprcsents the case, beneathand within which the wheel v.B revolves on an annular gate, .0, thattits ou and over the vcase being opened. for .the purpose. p

Said case 'A is composed for the most part of a cen-` ter plate, a, downthrough which the shaft b of the wheel passes, and a raised ,outer`hollow rim, c, having atransverse section of an inverted V, or otherequivaientV shape, within and below which the buckets ofV heel travel. i'Inis raised outer hollow `is fitted over or rests upon thelatter, andis constructed with outer and inner beveling, peripherieal sides cf,`.anda` ceutrtdvertical iiange lor rm, g, which i is connected withthe sides e and f by forwardlyinclined chutes It arranged alternately,as regards the l opposite sides of the vertical flange, so as to formalternately-arrauged openings t', corresponding inl number with theVopenings l in the case, over which,

when the gate isopenedby turning, 'they lie, bnt'areout ot communicationwith when tlie'gate is closed,v

the bases of the chutes It then covering the openings d. In this way thewater is admitted to and its supply regulated or shutoff from the wheel.Any suitable means may be used for turning the D rim cis provided onits` reversely-slopmg sides' with obliquely-tormed openings gate, acurved rack and piniou, as shown in the drawing, however, answeringevery purpose.

rlhe chutes h, it may be observed, are constructed to direct the water not only downwardly aud forwardly, but laterallyn reverse directionstoward the centers ot' the buckets.

The wheel B is composed for the most part of au open centerand of innerand outer rims k and l, with the buckets m in between them.

These rims extend downward in line, or thercabout, with the lower edgesof the hollow riln c of the ease, and to` unequal depths, the outer rimZbeiug made deeper thanthe inner rim k.

The buckets an, which correspond in number to the opening l andz'u thecase and gate, are of a hollow form, and sit incli'ning upwardly in aforward direction; also, are made pointed -at their rupper ends,conformingto the shape of the hollow rim c, within which they travel,and are preferably corrstructcd to extend below the outer rim Z ofthewheel.

The gate G' being opened the water is conducted,

-by the chutes h and openings (l and i, to strike or press upon thebuckets, both forwardly, downwardly, and in reverse lateral directionstoward the Centers 0f them, giving a most eiiieient action, and isdiscl'iarged from the buckets not vonly downwardly and outwardly, butalsocentrally, thus relieving the wheel cal rims e and j', and providedon opposite sides, be-

tween said rims, with alternately-arrangcd openings i andalternate]y-disposcd chutes t, constructed to direct the waterdownwardly, forwardly, and in reverse lateral directions, essentially asherein set forth;

3. The hollow buckets 'unset to incline upwardly in a -forwarddirection, and made pointed at their up per ends, in combination withthe raised hollow rim of the case A, essentially as described. ELLER-YC. BOYLES.
